Since Cids are already cryptographic-hash-based objects, it makes sense not to do too much extra work hashing them again when used as HashMap/HashSet keys; the hash_hasher crate could be used to improve the performance.

Ideally, we'd take a page from the https://github.com/multiformats/js-multiformats book and support cjs, esm, etc builds via rollup and friends to support multiple platforms/use-cases. Since this is designed to be a light-weight alternative to other ipds-based libraries, it should have a really low barrier to usage out of the box. In fact, moving forward, this should be a pretty critical require

Another possible method of filtering data would be using bayesian classification such as https://github.com/lytics/multibayes.

To complete this issue research should be done to see if this provides any notable benefits, and if so provide a small prototype of the functionality.

The ls and resolve commands shows my .pinset entry as having a size of 60. Let's force it to add units in all cases.

Currently the FileAPI is only capable of uploading single files, we should enable directory uploads
